To all whom it may concern: 1

Be it known that I, ANTON. Bscxnn, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Underframes for Cars; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled the art to which it appertains to. make and use the same.

My invention relates to improvements for underframes for came-one object of the invention being to provide means whereby an underframe can be adapted to trucks of more than the usual height so that the coupcoupling devices on cars having trucks of standard height.

A further object is to insure the proper alining of the outer ends of the bolsters and cross-bearers of an underframe and insure the rigidity of the latter.

With these objects in view the invention consists in certain novel features of construction andcombinations of parts as hereinafter set forth and, pointed out in the In the accompanying drawings, Figure 1 is a transverse sectional view of a car, taken adjacent to one of the crossrhearers. Fig. 2 is a similar view adjacent to tion of a car. I

1 represents the center girder, comprising channels from the respective channels of the center girder, each' and secured to the members I of the center girder by means or angle-brackets 4.

A tension plate 5' is disacross the top of the center girder and is bolted to. the upper flanges of said cross-bearer members. Diaphragms 6 are secured at their upper edges to the cross bearer members and are provided at their inner ends with flanges 7 lying against the outer faces of the center.- girder membersmA filler 8 isdisp'osed between the diaphragms, through the center girder members and I through the flanges 9 of the snore. Flanges 1 1 projegt laterally from the inclined loweredges of the dia phragms 6 and to these a compression plate 12 tending across the bottom of the center girder.

Each bolster oi the underframe comprises two pairs .of channel members 13 secured at their inner ends to the sides of the center girder by means of angle brackets 14. A tension or cover plate 15 is mounted upon the bolster, secured-to the flanges of the members there- Specification of Letters Patent; Application filed May 10,1901. Serial to. 372,940.

Patented Aug. 20, 1907-.

In order to adapt the'underfiame to trucks of more than usual height, the members of the center girder are recessed, as shown at 16, and between the center girder I members, above the recessed portion 16, a casting 17 is secured and made with a socket 18 for the reception cf the upper end of the pin which connects the underframe with thetruclr. Angle-bars 19'are secured to the outer faces of the center girder members immediately over the re cessed portions of the latter. Diaphragms 20 are secured at their upper edges to the bolster members and at their inner ends are provided with' flanges 21 securely riveted to the angle-bars 19. The intermediate portion 02 a compression plate 22 (preferably heavier or thicker than the compression plate 12 secured to the crossbearerdiaphragml, has its intermediate portio'npassing through the recesses 16 of the center girder members and bearing against theoutwardly projecting members of. the angle-bars 19. This compression plate 22 extends in both directions from the center girder to points in proximity to the outer ends of the diaphragms 20 and ar' bolted to the flanges .23, projecting laterally, from the inclined edges of said diaphragms. A bottom plate 24, adapted for cooperation'with a truck, is 16- cated within the recessed portion 16 of thecntr girder and'provided with flanges 25. Bolts 26 pass through these flanges, the compression plate 22 and the angle-bars 19 for securing the bottom plate 24 in place, By'nieans of the construction above described I amenabled to mount the underh-ame upon trucks of more than standard height and. to compensate for the difference in; height between suchh'ucksand those commonly employed, to insure proper alinement of the coupling devices between cars. I

Angle-iron members 27 located at respective sides of 9b the .underframe, extend from one end tosthe other of the car underframe and are secured to the outer ends of the cross-bearer members and the bolstermembers by means of angle-brackets or gussets 28. The upper horizontal portions of the angle-iron bars or members project over the ends of the cross-bearers and bolsters I and have the side stringers 29 secured upon them. Intermediate stringers 30 are mounted upon and secured to .the cross-bearers'andbolsters by means of bolts which also secure the flooring 31 upon the string-' ers. Angle-iron bars or members 32 connect the anglemembers or bars 27 at the ends of the underframe; are located behind the end sills 33 and are secured to the center girder by means of angle-brackets 34,--sai d angle-members or bars 32 thus constituting abutments for the end sills, and the'angle-members 27, at I the sides of the underirame,. insuring the proper aline- I ment or the cross-bearers and bolsters and'the rigidity .of-saidunderframe.

F ght might made in the details 1100* of myinvention Without departing from the spirit thereof or limiting its scopenndhence I do not wish to restrict myself to the precise details herein setlorth;

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,-

-1. A car underfrqme comprising a centergirder, crossbearers and bolsters secured to the center girder, angle bars secured to the ends of the cross-bezirers and bolsters and extonding'from end to end of the nnderframe, and

'angle-bars at the ends of snid under-frame and extending means securing said angle bars to the center girder.

-- In ucar underfrnnie, the combination of a center girder, bolster members secured thereto, said center girder having a recessed portion below the bols'ter, diaphragms secured-to the bolster members, and a compression plate extending through the recessed portion of the center girder and secured to said diaphragms.

4. in a car undertrame, the combination of a center girder. bolster members secured thereto, said center girder recessed below the bolster, reinforcingangle-bars secured to the center girder over the recessed portion thereof, diaphragrns secured to the bolster-members and to said reinforcing anglebnrs, and a compression plate disposed under said anglebnrs, passing through the recessed portion of the center girder and secured to the bolster diaphragms.

5; In a car underfrnme, the combination of a center girder, bolster'mcinbers secured thereto, said center girder recessed below the bolster, angle-bars secured to the center girder over the recessed portion thereof, a compression plate passing through the recessed portion of the center girder, bolster diaphragms secured to the bolster members and to said compression plate, and a bottom plate for cooperation withn truck, secured to said compression plate. in testimony whereof, I have-signed this specification in the presence of two subscribing Witnesses.
